论文摘要
通过静电束偏转法研究了深呈咪唑（IM）分子，二聚体和三聚体。监视（IM）D+的挠度曲线提供了一种直接的方法来确定它是（IM）2和（IM）3中的电离引起的片段的主要产物。挠度的大小决定了母体簇的电偶极矩：二聚体近9 d，三聚体14.5 d。这些非常大的偶极子值证实了理论预测，并源自杂环咪唑分子的极性链键合布。
Deuterated imidazole (IM) molecules, dimers and trimers formed in liquid helium nanodroplets are studied by the electrostatic beam deflection method. Monitoring the deflection profile of (IM)D+ provides a direct way to establish that it is the primary product of the ionization-induced fragmentation both of (IM)2 and (IM)3. The magnitude of the deflection determines the electric dipole moments of the parent clusters: nearly 9 D for the dimer and 14.5 D for the trimer. These very large dipole values confirm theoretical predictions and derive from a polar chain bonding arrangement of the heterocyclic imidazole molecules.
